Tebuconazole 45% WP
Broad-spectrum triazole fungicide for sustainable crop protection
Product Overview
Tebuconazole 45% WP is a systemic fungicide formulated as a water-dispersible powder, offering exceptional protection against a wide range of fungal pathogens. Developed for modern precision agriculture, it combines rapid action with long-lasting residual control.
Key Advantages:
Dual mode of action: inhibits ergosterol biosynthesis and disrupts fungal cell membranes
Cross-crop versatility for cereals, fruits, and vegetables
Rainfast within 2 hours of application
Compatible with integrated pest management (IPM) programs
Features & Benefits
Technical Superiority
Enhanced Systemic Mobility: Rapid uptake by roots, stems, and leaves
Resistance Management: Triple-site enzyme inhibition (CYP51, CYP4, CYP2)
pH Stability: Maintains efficacy across pH 5–8 spray solutions
User Benefits
Reduced application frequency (14–21 day residual activity)
Tank-mix friendly with most herbicides and insecticides
Minimal phytotoxicity risk when used as directed
